Are you a graphic designer itching to tweak your shop's layout, or throw some fancy graphics into the mix?  Well, get ready, because the wait is over.  You can now upload your own CSS stylesheet to control every aspect of your shop's design.  Just go under "My Shops", select your shop, and choose "Customize Shop".  You'll see the "Custom Stylesheet" field.  Upload a CSS stylesheet, and you're off!

Keep in mind that this feature is for experts only.  Consider it the equivalent of a black diamond ski slope.  If you're not careful, it could make your shop look strange, break functionality, or burn your toast.  Consider yourself warned, and happy customizing!
